ICE-CRE AM FREE ZER.

T0 all whom it may concern:

Be it known that I, FREDERICK I. BURR, a citizen ol' the United States, residing at Middletown7 in the county ot' Middlesex and State ol' Connecticut, have invented a new and usel'ul Improvement in Ice-Cream Freez ers; and I do hereby declare the following, when taken in connection with the accompanying drawings, and. the numerals ol' relerence marked thereon, to he a t'ull, clear, and exact description ol` the saine, and which said drawings constitute part ol' this specification, and represent, in-

Figure 1 a top or plan view oi' an ice cream l'reezer having three containers, the support- Vlor one el.' the containers heing turned back. Fig. 2 a hroken l'ront view showing a side view ol' one ol the containers and a sectional view ol.l another container. F 3 an end view oll the l'reezer with the operating har in its lowest position. i

This invention relates to an improvement in ice cream freezers and is an improvement on the l'reezer shown and described in U. S. Patent No. 637 ,078 granted to me November 14, 1899. In my previous patent the can was supported in a tuh or pail and adapted to he rotated hy having a cord attached to the neck on the top olI the can around which neck the cord might he wound and so that hy drawing the cord outward the can would he rotated and given sutl'icient rotary l'orcc to wind the cord in the opposite direction and so that hy repeatedly drawing the cord outward and allowing it to he wound upon the central hearing the can or container would he constantly rotated tirst in one direction and then in the other.

The ohject of the present invention is to provide simple means l'or operating the cord and to provide l'or a series or hattery of cans or receptacles wit-hin the same tuh, and so that ditl'erent kinds or lavors otl cream or ices can he l'roZen at the same time; and the invention consists in certain details of construction and arrangement ol' parts as will he hereinafter described and particularly recited in the claim.

In carrying out my invention I provide a tuh 2 of suitable size and shape to hold the desired nuinher et' cans. For convenience ot illustration I have shown a tuh with three cans or containers. Mounted in the hottom ol' the tnh are three guards 3 ol perforated Specification of Letters Patent.

metal or wire netting. These guards are secured to the hottom 5 ol' a tuh hy screws 6 which have large heads 7. These guards are larger in diameter than the cans or containers S which set into them, and the cans are formed at their lower ends with sockets 9 to set over the screw heads 7 wherehy the cans or containers are centered. These cans have tight locking covers 10 l'ormed with necks 1l to which operating straps 'l2 are secured and around which the straps may he wound in the saine manner as in .my previous patent. The tops ol the cans are supported in any desired way; as herein shown hy transverse locking strips 13 which are hinged to one side ol' the tuh and interlocked with the opposite side and l'ormed with sockets 'ist to engage with the necks 11 wherehy the cans are supported in a vertical position, hut l'ree l'or rotation.

Ilinged to hrackets l5 secured to the l'ront ol' the tuh are arms` 1G supporting a har 1.7 having hooks 1S with which rings 1Q secured to the ends ol' the st-raps 12 may engage and so that all the cans or containers in the tuh may he rotated at the same time. By moving the har away vfrom the tuh the straps 12 are drawn outward, thus turning the cans in one direction and with such l'orce that hy the continued rotation the straps will he wound in the opposite direction, it heing understood that the har 17 will he raised or allowed to he lil'ted hy the strap when the rewinding takes place and when rewoundr another outward movement oll the har 17 will rotate the containers in the opposite direction.

Il for any reason it is desired to examine the contents ol' one can the strap ol that can may he disengaged vl'rom the operating har and that can opened without disturbing the movement ol' the other cans.

It will thus he seen that one or more ol' the cans may he operated without interfering with the other cans, so that cream may he `l'rozen in one or more cans while the remainingl cans are at rest. v

It will he understood that the tuh around the guards will he packed with ice and salt in the usual manner ol' freezing cream. The guards keeping the ice away 'from the cans, allows the saline solution to come in Contact with the cans, and consequently the coutents will he l'rozen more rapidly than ilthe ice Were in Contact With the cans and the ice does not interfere With the rotation of the cans.

I claim:-

An ice cream freezer comprising a tub, a plurality of containers mounted in seid tub and capable of rotation therein, a strap connected With each container, a bar hinged to said tub, and Ineens for detaehably connecting said straps With said bar, substantialiy IO as described.

In testimony whereof, I have signed this specification in the presence of two subscribing` Witnesses.
